从Rails 5.1.6升级到Rails 5.2.0以及422错误的响应页面后，我的生产服务器上针对所有POST请求都收到以下错误：
public class E : VisualCommanderExt.IExtension
{
public void SetSite(EnvDTE80.DTE2 DTE, Microsoft.VisualStudio.Shell.Package package)
{
this.DTE = DTE;
events = DTE.Events;
windowEvents = events.WindowEvents;
windowEvents.WindowActivated += OnWindowActivated;
documentEvents = events.DocumentEvents;
documentEvents.DocumentOpened += OnDocumentOpened;
}
public void Close()
{
windowEvents.WindowActivated -= OnWindowActivated;
documentEvents.DocumentOpened -= OnDocumentOpened;
}
private void OnDocumentOpened(EnvDTE.Document Document)
{
try
{
documentOpened = true;
}
catch (System.Exception)
{
}
}
private void OnWindowActivated(EnvDTE.Window gotFocus, EnvDTE.Window lostFocus)
{
try
{
if (documentOpened)
DTE.ExecuteCommand("Edit.CollapsetoDefinitions");
documentOpened = false;
}
catch (System.Exception)
{
}
}
private EnvDTE80.DTE2 DTE;
private EnvDTE.Events events;
private EnvDTE.WindowEvents windowEvents;
private EnvDTE.DocumentEvents documentEvents;
private bool documentOpened;
}
奇怪的是，即使服务器和本地都在Rails 5.2.0和Ruby 2.2.1上，在本地计算机上的生产模式下也没有出现这些错误。

上曾经有一个application_controller方法，它带有：：exception子句，像这样：
protect_from_forgery…但是我将其移至class ApplicationController < ActionController::Base
before_action :authorize_mini_profiler
require 'sass/rails'
protect_from_forgery with: :exception
没有异常子句的回调之前：
before_action现在我没有收到422错误的响应页面，但是日志中仍然包含class ApplicationController < ActionController::Base
protect_from_forgery
before_action :authorize_mini_profiler
require 'sass/rails'
错误，用户无法登录其帐户。
这个错误是如此神秘，在哪里看？
